Also i think GE silicone #1 is what you want, likel you suspected. I think its #2 that has additives for fighting mold. Either way you want the one thats pure silicone with no additives on the chance they leach into your water
Did I find a steal or... ?

For reference, the glass is the exact same thickness as that on my 20Tall, which is only 1" shorter than this oddball tank. I did notice that the bottom is built the same as every other glass tank, with the glass bottom sitting about 1/2" higher than the rim of plastic. I would definitely feel more comfortable with this if the glass could lay flush on my stand, which has a solid oak bottom.
I had never heard the height/thickness point before. I always thought it was volume/thickness. that's a very interesting thought.
I will be testing it outside full for a week or two. going to reseal it up tomorrow and let it cure till sat or sun, then fill it and forget about it for a while.
If it bursts, I'm only out $40, but I did get a neat heat lamp out of the deal as well that I can use in the spring.
Will let you know how it works out.

The pressure of the.glass comes from the weight of the water pushing against it. The force of water pushing against it depends on the height of the water column above that since water below that doesnt push up.
Anyhow thats why height matters. Obviously width and length play a big part since the longer they are the more glass will flex unless you have supports along the way

The pressure isn't soley based on height, its also length. Here's your link my friend:

Thank you for the link!!! That is an awesome chart!
Curious what the numeral "safety factor" represents. My glass is indeed the 6mm at 4'length and <18" height shows a factor of 2.05. I read through all 15 pages and could find no reference as to what the value of safety factor represents. also curious that an 8' tank of up to 18" depth still minimum requirements of 6mm That is reassuring, but there are no structural supports in the tank i'm working with. but either way, Thank you very much for that link, it is already on my bookmark list.
